RAZOR-BLADE HOLDER.

Specification of Letters Patent.

Patented April 14. 1908.

Application filed July 31, 1907. Serial No. 386,377.

To all whom it may concern:

Be it known that I, PATRICK JOSEPH EA? RIGHT, a citizen of the United States, residing at Lowell, in the county of Middlesex, State of Massachusetts, have invented certain new and useful Improvements in R azor-Blade Holders, of which the following is a description, reference being had to the accompanying drawing and to the letters and figures of reference marked thereon.

This invention relates to holders for the blades of safety razors, and has for its principal object to provide a holder of very simple construction, which will firmly clamp and retain thin flexible blades of the Gillette type, during the stropping or honing operations.

A further object of the invention is to provide a novel construction of holding clamp in which the clamping members are of such nature as to provide an interlock, without any projection which would engage with and tend to injure the strap or hone, and which at the same time will effectually clamp and hold the blade from accidental displacement.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings: Figure 1 is a perspective view of a razor holder constructed in accordance with the invention; Fig. 2 is a transverse sectional view of the same; Fig. 3 is a side elevation, showing the clamp partly open; and Fig. 4 is a detail View of the locking device.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

. The holder comprises aZ-lamping plate 10, that is preferably formed of thin sheet metal, and is concavo-convex in cross section, presenting two relatively sharp gripping edges for contact With'one face of the blade 90.

The rear end of the arm 10 is formed integral with a tapered ferrule or sleeve 11 that fits on a carrying and operating handle 12, that may be formed of any desired material. The extreme outer end of the arm is flattened,

a distance about equal to the thickness of the blade.

The second or movable clamping arm 17 is formed of die struck sheet metal,. and it is,

also, concavo-convex in cross section to present a pair of clamping edges opposing those of the arm 10. The outer end of the arm 17 is provided with an opening for the passage of the pin 15, and the arms are opened and closed by a swinging movement in a direction parallel with the plane of their clamping surfaces.

The arm 17 .is sprung in the direction of its length, vso as to present a convex surface to the blade when the arm is in open position, as more clearly shown in Fig, 3, and in order to movethe arm to closed position,- it becomes essential to press down on its free or inner end, and then swing the arm on the pivot 15. In this manner, the convex face of the arm is forced down gradually on to the surface of the razor blade, so that the latter is clamped and held positively throughout its entire length.

In. order to hold the inner end of the arm 17, said arm is providedwith a projecting tongue 18, the end of which is disposed obliquely to the transverse )lane .of the arm, and this tongue is arrange to fit within a recess that is formed under shoulders 19 out in the end of the ferrule or sleeve 11. In order to make this look more positive and increase the strength of the free end. of the arm, the tongue 18 is preferably formed of a separate block of metal that is soldered or otherwise secured. within the end of the arm proper. The extreme end of the shoulder 18 is obliquely dis osed as before described, and the end wall 0 the recess is correspondingly inclined, so as to form a stop with which the end of the tongue engages, in order to limit imposed on the studs 1,6 that are carried by l movable arm, and a locking shoulder carried the rigid arm 10.

, The outer faces of the arms being convex, will freely slide over the strap or hone, and they stand out a sufficient distance to hold the blade at the proper angle to the surface. The locking or connecting means between the arms offer no projections to engage with the strap or hone, so that danger of injury from this cause is avoided.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent, is

1 A razor holder, comprising a pair of arms, concavo-convex in cross section to present a pair of parallel clamping edges, means for. pivoting the outer ends of the arms together to permit separation and closure of the arms in a direction parallel with the plane of their clam ing surfaces, and means for interlocking t e free ends of the arms.

2. A razor holder, comprising a pair of arms tpivoted together at their outer ends, one 0 said arms having an integral handle member and the other being initially curved i or sprun to present a concavo-convex surface to t e blade to form arallel clam ing edges, a tongue carried by t e free end 0 the by the handle member and with which said tongue engages.

3. r In a razor holder, a clamping arm formed of sheet metal, and concavo-convex in cross section to present a pair of parallel clamping edges, a sleeve or ferrule 'fornicd integral With said arm and provided with an inclined tongue-receiving slot and a shoulder, the outer end of said arm being flattened, a second movable clamping arm also concaveconvex in cross section, and having a flattened outer end that is pivoted to the outer end of the stationary arm, the movable arm being sprung or curved in the direction of its length to present a convex surface to the blade, a tongue projecting from the free end of the movable arm, the end of the tongue being inclined to correspond to the inclination of the Wall of the slot, and a pair of razor blade engaging studs projecting from the stationary arm. I

In testimony whereof I a'flix my signature in presence of two witnesses.
